Struct Permissions_type

pub struct Permissions_type(/* private fields */);

Represents the permissions of a file or directory.

The permissions are divided into three groups: user, group, and others. Each group has three permissions: read, write, and execute.

Examples

use File_system::{Permissions_type, Permission_type, Special_type};

let user = Permission_type::New(true, false, false); // Read only
let group = Permission_type::New(false, true, false); // Write only
let others = Permission_type::New(false, false, true); // Execute only
let special = Special_type::New(true, false, true); // Sticky and set user identifier

let permissions = Permissions_type::New(user, group, others, special);

assert_eq!(permissions.Get_user(), user);
assert_eq!(permissions.Get_group(), group);
assert_eq!(permissions.Get_others(), others);
assert_eq!(permissions.Get_special(), special);

pub const fn New( User: Permission_type, Group: Permission_type, Others: Permission_type, Special: Special_type, ) -> Self

Creates a new permission.

pub const fn New_default(Type: Type_type) -> Self

Creates a new permission with read access for user. No access for group and others.

pub fn Set_user(self, User: Permission_type) -> Self

Sets the permission for the user.

pub fn Set_group(self, Group: Permission_type) -> Self

Sets the permission for the group.

pub fn Set_others(self, Others: Permission_type) -> Self

Sets the permission for others.

pub fn Set_special(self, Special: Special_type) -> Self

Sets the special permissions.

pub fn Get_user(&self) -> Permission_type

Gets the permission for the user.

pub fn Get_group(&self) -> Permission_type

Gets the permission for the group.

pub fn Get_others(&self) -> Permission_type

Gets the permission for others.

pub fn Get_special(&self) -> Special_type

Gets the special permissions.

pub const fn From_octal(Unix: u16) -> Option<Self>

Converts the permission to a Unix permission.

pub const fn As_u16(&self) -> u16

Converts the permission to a Unix permission.

Trait Implementations

impl Clone for Permissions_type

fn clone(&self) -> Permissions_type

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Permissions_type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Permissions_type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Permissions_type

fn eq(&self, other: &Permissions_type) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
